Hi Shawn,
With generic DMA device tree binding and helper function dma_request_slave_channel() in place, dmaengine_pcm should support that in requesting DMA channel for users that support generic DMA device tree binding.
Add a new API snd_dmaengine_generic_pcm_open() as the variant of snd_dmaengine_pcm_open(). It takes DMA client struct device pointer and slave channel name as arguments and calls generic DMA helper dma_request_slave_channel() to request DMA channel from dmaengine.
